 * rl-article.css —— 文章页共享样式表（由 head 内联外链化）
 * 迁移日期：2026-08-27
 * 来源：wp-content/mu-plugins/rl-home-styles.php 的 wp_head 钩子（原第 2158-7446 行）内联 CSS，原始 148,683 字节
 * 去重规则：仅删除字节级完全相同的（媒体上下文+选择器+声明块）重复，每组保留最后一份出现（级联语义等效）；
 *          所有不同变体按原顺序全部保留——包括无前缀 .breadcrumb（变体A）与 .article-container .breadcrumb（变体B，全 !important）两个面包屑变体；
 *          未对任何非字节级相同的规则做修改、合并或取舍。
 * 加载方：mu-plugins/rl-article-css.php，仅 is_singular('post') 时以 filemtime 版本号 enqueue。

   新规范文章标题恢复（2026-09-09）
   背景：rl-article.css 内有 `.entry-header:not(.article-container .entry-header){display:none}`
   会把 Astra 主题输出的文章标题区隐藏。旧文章正文自带 <h1> 不影响；
   新规范文章正文禁用 <h1>、靠主题标题显示，但不含 .article-container，
   故标题被隐藏。mu-plugins/rl-article-css.php 为正文含 .rl-article 的文章
   加了 body 类 rl-spec-article，下面据此放开标题（存量 + 未来文章统一生效）。
   ============================================================ */

   2026-10-01 新增：文章内宽表格的窄屏局部横向滚动支持
   背景：本文件全局 table{min-width:720px} 要求外层有 overflow-x:auto 容器
        (.table-wrap / .table-wrapper)；旧文章的裸 <table> 缺这层容器时，
        窄屏会被 body 的 overflow-x:hidden 裁切且无法滑动，右侧列不可达。
   做法：窄屏给表格套 .table-wrap.rl-table-scroll 做局部横向滚动 + 滑动提示；
        桌面端（>=821px）让容器 overflow:visible，保持表格原有排布不变。
        不隐藏列、不缩字号、不改任何既有选择器。
   ============================================================ */
